- Protein1-aminocyclopropane-1-carboxylate oxidase 1
- GeneACO1
- StatusUniProtKB reviewed (Swiss-Prot)
- Amino acids310 (go to sequence)
- Protein existenceEvidence at transcript level
- Annotation score4/5
Function
function
Enzyme involved in the ethylene biosynthesis. May promote stem elongation by maximizing the extensibility cells, possibly by activating ethylene biosynthesis, in response to very-long-chain fatty acids (VLCFAs C20:0 to C30:0).
Catalytic activity
- 1-aminocyclopropane-1-carboxylate + L-ascorbate + O2 = ethene + L-dehydroascorbate + hydrogen cyanide + CO2 + 2 H2O
Cofactor
Note: Binds 1 Fe2+ ion per subunit.
Pathway
Alkene biosynthesis; ethylene biosynthesis via S-adenosyl-L-methionine; ethylene from S-adenosyl-L-methionine: step 2/2.

Expression
Induction
Upon potassium K+ and iron deprivation. Induced in leaf blades in low light intensities. Seems repressed by ethylene. Accumulates in response to very-long-chain fatty acids (VLCFAs C20:0 to C30:0). Induced in roots by nitric oxide (NO).
